ABSTRACT:
The present invention provides a pump by vessel oscillation including a vessel having an inlet for liquid and an outlet opening in a specific tangential direction of an outer peripheral portion thereof. The vessel is oscillated in a specific direction to outflow the liquid through the outlet opening. Accordingly, the liquid in the interior of the vessel undergoes a simple centrifugal motion and when the pump is used for a blood circulation device such as an artificial heart or assisted circulation device, the blood is completely shut off from outside and isolated from entry of various germs, air, foreign matter, etc. The pump is simple is construction and excellent in reliability and durability.
